I have the same problem and it is very annoying. I do not want the preview but only the name of the sender. On the S3 there is an option on message setting, but it disappear on the S4. Any suggestions?

I have the same problem, I have gone from Iphone 5 to S4 this weekend and I miss this feature, I don't want the message previewed - just the name shown before I open the text.
Seems odd if the S3 allows it but not the S4?

Its all a bit new to me as I have been an Apple user for a lot of years - finally gone to the other side! LOL

Im just a new S4 user too. I think this is the solution to the previewed sms on the home screen. Just go to your Messaging then press Menu select Settings look for the Notification Setting and remove the check on Preview Message.
